FORMULE DE VERIFICARE:

Verificare sectiune

Inima: (h0/ti) / (h0/ti)max = 20.00/168.94 = 0.12 < 1.0; Talpa: (b'/t) / (b'/t)max = 20.00/141.15 = 0.14 < 1.0 [12,13] SECTIUNE SCURTA

(N/A + My/Wy + Mz/Wz)/(1.1*R) = 0.19 < 1.00 [8.1.3-(8.4)]

Tauy,mid/Rf = 0.03 < 1.00 [7.1.1-(7.3)]; Tauz,mid/Rf = 0.03 < 1.00 [7.1.1-(7.3)]

Verificare stabilitate element

Lamy = 46.68 < Lamy,max = 120.00 Lamz = 46.68 < Lamz,max = 120.00

[N/(Fi*A) + Mefy/(Fig*Wy) + Mefz/Wz]/R = 0.59 < 1.00 [8.2.3-(8.8)]
